Others you are expected to install first if you want Audacity to have certain capabilities. Most of these libraries are not distributed under the terms of the GPL, but rather some other free, GPL-compatible license. Specifically: wxWindows: LGPL Cross-platform GUI library - must be downloaded and compiled separately. expat: BSD-like license. Provides XML parsing. Included with Audacity iAVC: LGPL Part of the code to the AVC Compressor effect. Included with Audacity. libid3tag: GPL Reads/writes ID3 tags in MP3 files. Optional separate download as part of libmad. libmad: GPL Decodes MP3 files. Optional separate download. libnyquist: BSD-like license. Functional language for manipulating audio; available within Audacity for effects processing. libogg: BSD-like license. Optional separate download, along with libvorbis. libsndfile: LGPL Reads and writes uncompressed PCM audio files. Included with Audacity. libvorbis: BSD-like license. Decodes and encodes Ogg Vorbis files. Optional separate download. For more information, see the documentation inside each library's source code directory. ------------------------------------------------------------- Compilation instructions: First you must download wxWindows from: http://www.wxwindows.org/ If you install the RPM, make sure you install the devel RPM as well, otherwise, you won't be able to compile Audacity from source. To compile on Linux, Mac OS X, and other Unix systems, simply execute these commands: ./configure make make install # as root To see compile-time options you can set, you can type "./configure --help". If you want to do any development, you might want to generate a configure cache and header dependencies: ./configure -C make dep To compile on Windows using MSVC++, please follow the instructions found in compile.txt in the "win" subdirectory. For more information on compilation (CodeWarrior for Mac is also supported) please email audacity-help@lists.sourceforge.net ------------------------------------------------------------- Known issues/problems: * Windows: The floating tool palette does not minimize when minimizing a project window. As a workaround, you can just keep the tool palette docked with the project window. ------------------------------------------------------------- New features in Audacity 1.1.3: * User Interface - New Mixer toolbar allows you to control the output volume, input volume, and input source directly from Audacity. - Every track now has its own gain and pan controls. * File I/O - Uses improved project file format. (Unfortunately reading previous formats, including 1.1.1, is not supported.) - Block files (stored in Audacity project directories) now use the standard AU format. Though some Audacity meta-information is in these files, they can now be read by many other popular audio programs as well. - Fixed some bugs relating to reading/writing audio files with more than 16 bits per sample. - Import RAW is functional again, with a simpler GUI but support for far more file formats. The autodetection algorithms are much more accurate than in 1.0. * Audio I/O - Completely rewritten audio I/O, with lower latency and minimal chance of buffer underruns while recording. * Resampling - Using high quality resampling algorithms, with the option of better quality for mixing than for real-time playback - Preliminary support for Time Tracks, for changing playback speed over time. * Many more bug fixes and new features New features in Audacity 1.1.2: * User Interface - Fixed bug in Windows version, for track menu commands "Name..." and "Split Stereo Track"/"Make Stereo Track". * Effects - Nyquist support on Windows (supports plug-ins written in Nyquist, an interpreted functional language based on Lisp). New features in Audacity 1.1.1: * User Interface - Tooltips appear in Statusbar. - Vertical cursor follows play/record - Pause button - Drawing tool (with three different modes) - Vertical Resizing of stereo tracks is more fun. - Adjust selection by click-dragging selection boundary - Toolbar button context-sensitive enabling/disabling - Better zooming functionality (centers region) - Multiple ways to display the cursor position and selection - Snap-to selection mode - Drag tracks up and down - Align and group align functions - Cursor save/restore - Working history window * Effects - Effects broken down into three menus: Generate, Effect, and Analyze - Generate menu lets you generate silence, noise, or a tone - Nyquist support (supports plug-ins written in Nyquist, an interpreted functional language based on Lisp) * Localization - Improved localization support - More languages available - Language selection dialog on startup * Mac OS X - Support for more audio hardware - Support for full-duplex (play while recording) - Support for MP3 exporting using LameLib Carbon * Unix - Audacity now has a man page (it describes command-line options and how to set the search path) * File Formats - Uses libsndfile 1.0, which fixes some bugs and improves performance * Searching for Files: - On Windows and Mac OS, Audacity now looks for translations in the "Languages" folder and all plug-ins in the "Plug-ins" folder, relative to the program. - On Unix, Audacity looks for translations in /share/locale and looks for everything else in /share/audacity and also in any paths in the AUDACITY_PATH environment variable New features in Audacity 1.1.0: * Core audio processing: - Support for 24-bit and 32-bit sample formats - Automatic real-time resampling (using linear interpolation) * Effects: - Support LADSPA plugins on Linux / Unix * File formats: - New XML-based Audacity project format - Full Ogg Vorbis support now (importing and exporting) - Export to any command-line programs on Unix - Support for reading and writing many more types of uncompressed audio files, including ADPCM WAV files. * Toolbars - New toolbar drawing code; automatically adopts your operating system's colors - New toolbar buttons (Skip to Start, Skip to End) - New Edit toolbar - Toolbar buttons disable when they're not available * User Interface - Fully customizable keyboard commands - Autoscroll while playing or recording - New Ruler, used in main view and in FFT Filter effect - The waveform now displays the average value in a lighter color inside the peak values * Localization - Audacity can now be localized to different foreign languages. New libraries in Audacity 1.1: * libmad for fast MP3 importing * libid3tag for editing MP3 file information * libsndfile to read and write more audio file formats * PortAudio for cross-platform audio playing and recording
